The separation effects of different types of PTMS magnetic separation devices on different magnetic minerals vary greatly. For example, iron remover is mainly used to remove mixed iron block or iron chips from the material flow, there are two types of electromagnetic and permanent magnet, suitable for iron removal with less iron. Magnetic pulley (magnetic drum) can separate the ore particles according to the different magnetic strength of the ore. Permanent magnet pulley has simple structure, does not consume energy, reliable work, easy to repair, and is widely used.
Different magnetic minerals have different magnetic strength, which is the fundamental factor affecting the effect of PTMS magnetic separation separation. For example, magnetite is a strong magnetic mineral, while hematite and limonite belong to weak magnetic minerals, and siderite is weaker. Strong magnetic minerals can be effectively attracted under a weak magnetic field, while weak magnetic minerals require a stronger magnetic field or special treatment to achieve better separation.
This magnetic difference determines the choice of PTMS magnetic separation devices as well as the setting of parameters such as magnetic field strength. If the magnetic difference between minerals is not obvious, such as some weak magnetic minerals, it is difficult to achieve efficient separation solely by magnetic separation, which may need to be combined with other mineral processing methods, such as flotation and reseparation, etc.
